Beam Behaviour and Magnetic Field of K500 SCC

The extraction of the beam from the k500 Superconducting Cyclotron in kolkata is posing a great challenge. After getting the internal beam, lots of effort were made to extract the beam and thereafter various experiments were designed and done to know the beam behaviour and to investigate the real reason. the deflector electrode was used in the Faraday cup mode. the deflector probe, bore scope probe and the main probe were used to investigate the beam behaviour by varying the first harmonic amplitude and phase with the help of trim-coil no.13 by operating it in harmonic mode. Finally magnetic field mapping was done. In this paper, all these experimental results are described in detail
